Yes and no. "Setting black and white points" usually means setting a
"white" point to an RGB complement in the range of 244-255 and black to
0-10. You have to have a dark and light point, but the appropriate one may
not be in this range. The black usually is (again, not always), but the
white may not be.
For film scanning, I use Vuescan, which gives one an option of "white
balance," "auto," and just "none". I sometimes try "white balance" but
usually use "none." I tend to prefer using Photoshop's control for these
things anyway.
